The term rollover is used exclusively for FX positions. Rollover fees are charged on FX positions held overnight. Rollovers are charged daily, weekend rollovers are calculated on Wednesday. However, please note that the rollover calculation is based on the balance of the previous (closed) trading day.
The rollover is calculated as (current notional value x * rate * days) / 360.
You can always check the rollover and overnight fees that may be applicable to your account in your client's area on exante.eu:
